This Compression Bit combines both up-cut and down-cut flute geometry to deliver chip-free edges on the top and bottom surfaces of your workpiece. With an 8mm cutting diameter and 22mm cut length, it’s engineered for CNC routing, joinery, and furniture production—pulling and pushing chips toward the centre for a stable cut and crisp finishes on plywood, MDF, solid timber, and laminates. Key benefits Chip-free edges top and bottom — up-cut + down-cut flutes minimise tear-out on both faces. Advanced nano coating reduces friction and heat build-up, allowing higher feed rates and longer edge life. 2-flute design provides a smooth finish, stable cutting, and consistent chip evacuation. Ideal for CNC routing of wood, MDF, plywood, laminates and non-abrasive composites. Two tools in one — up-cut lifts chips; down-cut compresses fibres for a cleaner face finish. Performs in tougher jobs where standard bits dull quickly—excellent for hardwoods, plywood and plastics. .atlas-spec-table-wrap { padding: 5px; margin: 30px 0 0; border: 1px solid #000; border-radius: 16px; overflow: hidden; background: #161616; box-shadow: inset 0px 1px 2px rgba(255,255,255,0.5), inset 0px 1px 2px rgba(255,255,255,0.5), 5px 8px 10px rgba(0,0,0,0.5), 0 0px 1px rgba(0,0,0,0.5); } .atlas-spec-table { width: 100%; border-collapse: separate; border-spacing: 0; border: 0; margin: 0; background: transparent; } .atlas-spec-table th { background: #dca101; color: #000000; text-align: left; padding: 14px 16px; font-size: 14px; font-weight: 800; } .atlas-spec-table th:first-child { border-top-left-radius: 12px; border-top-left-radius: 12px; border-right: 1px solid rgba(0,0,0,0.2); } .atlas-spec-table td { padding: 14px 16px; border-top: 1px solid rgba(255,255,255,0.08); } .atlas-spec-table td:first-child { width: 42%; border-right: 1px solid rgba(255,255,255,0.08); color: #f2f2f2; font-weight: bold; } .atlas-spec-table td:last-child { color: #d6d6d6; } .atlas-spec-table tbody tr:nth-child(odd) td { background: #1f1f1f; } .atlas-spec-table tbody tr:nth-child(even) td { background: #161616; } .atlas-spec-table th:first-child { border-top-left-radius: 12px; } .atlas-spec-table th:last-child { border-top-right-radius: 12px; } Spec Result Diameter 8mm Cut Length 22mm Shank (Collet Size) 8mm Overall Length 38mm Flutes 2 Coating Nano (NaCO) Lower friction coating for cooler cutting The optional nano coating (or DLC variant) increases heat resistance and lubricity, helping chips slide away cleanly. This reduces heat build-up, keeps the edge sharper for longer, and enables higher feed rates in demanding materials. Reduced heat and friction means more consistent finishes and longer tool life—especially in plastics, plywood glues, and dense hardwoods. Versatility and benefits Thanks to its 2-flute compression geometry, this bit excels at dados, grooves, slots, mortises and edge trimming. A favourite among cabinetmakers, sign makers, and CNC hobbyists for cutting hardwoods, laminates, veneers and common sheet goods—helping you cut cleaner, reduce sanding, and improve productivity on nested jobs.
